Outlook unable to send more than 20 emails

Brass Contributor

Hi the community,

I hope you are all fine and safe.


I'm using the Outlook desktop client with a MS365 licence.


I have added a pop3 account and when I send, in one time, more than 20 emails only the first 20 emails are sent, the rest of the emails remain in the Sending Box. If I close Outlook and reopen it, the next 20 emails are sent and so on.


Do you know what is the problem and how to solve it. Thank you
